This invention is a tool for plunge cutting comprising a motor, a transmission connected to the motor and a blade assembly connected to the transmission, wherein the blades move in an oppositely reciprocating and sliding manner to provide plunge cuts of variable depth with closed ends and a continuous perimeter. The tool of the invention may be held and operated with one hand. The invention is designed to be held in juxtaposition to the area to be cut, and the invention further optionally includes a novel blade wherein the blades have opposite first and second sides, wherein the first side is completely flat, allowing it to slide unobstructed against the first side of the other blade; and wherein alternating teeth, including both end teeth, are straight and not bent or set; and wherein alternating even teeth are bent toward the second side of the blade; and wherein one-half of the teeth point forward and the other half of the teeth point aft; and wherein the blade teeth follow an arc; and wherein the front and aft edges of the blade are shaped to form a gullet.
